The best polyurethane foam for 2020

Modern materials allow for quick installation in construction. For example, without construction foam today it is not possible to fix various structures.

The substance fills any cracks and allows filling various cavities. These products are presented on the market in an immense range. The editorial staff of the site "bestx.htgetrid.com/en/" offers a rating of the best polyurethane foams for 2020.

What is polyurethane foam?

Foam is a versatile composite, polyurethane, which is enclosed in a pressure cylinder. There is no air inside the container, but when oxygen enters, the base immediately hardens. The insulator is dense, but porous. The substance has good sound and heat insulation functionality.

The foam is resistant to combustion, moisture and low electrical conductivity. Poor foam quality - high sensitivity to light streams. Due to ultraviolet radiation, the sealant loses its original color and structure.

Criterias of choice

The commercially available formulations vary in price and quality. When choosing, it is recommended to consider the following.

If you need the usual household version of the cylinder, you should choose the disposable options, which are accompanied by a tube. The substance inside does not have a good density, but it retains a given volume for a long time, so the product yield is quite significant.

There are reusable versions that require an additional device - a gun. With its help, you can adjust the amount of squeezed out substance, due to which the chemical composition is consumed rather moderately. One cylinder can be reusable, but the gun must be flushed after each use.

Summer chemical compositions are allowed to be used at above-zero temperatures from +5 to +40. Winter, frost-resistant version, can be opened at -20 degrees. There are all-season products with performance from -10 to +30 degrees.

The cans also contain a fire protection designation. For example, a product labeled B1 has refractory properties. The B3 mark indicates the flammability of the composition. This information is needed when treating chimneys and heating systems. For the optimal choice, the following main criteria can be distinguished:

• Safety;
• Specifications;
• Price;
• The opinion of the store's consultants;
• Customer reviews.

Types of polyurethane foam

The composition of the insulator can be one-component or two-component. The first option is more common, more convenient to use. All types of the presented options are one-component, sold in an aerosol can. The substance in the balloon is synthesized from ocyanate and polyol, as a result, it is a prepolymer.

The chemical reaction begins inside the container, but most of it is observed when substances come into contact with oxygen. This is where polyurethane is formed. The substance appears under the pressure of liquefied gas:

• Bhutan;
• Isobutane;
• Propane.

Thanks to the foaming agent, the volume of the substance increases by 20-40 times. Expansion is usually abrupt, so filling should be fast. The mass hardens faster in a humid room. It is known to moisten surfaces to increase the speed of the process. The standard period for the completion of a chemical reaction is a day. During this time, the mass turns into a stable polyurethane.

The finished substance has high strength, durability and harmlessness. The insulator can be used on a variety of surfaces:

• Concrete;
• Stones;
• Iron;
• Wood;
• Plastic.

With the help of foam, they achieve significant sound insulation, sealing, fixing the elements to each other.

Foam properties

The main quality of a polyurethane insulator is a multiple increase in volume. The degree of expansion for different materials varies from 10 to 60%, this is relative to everyday types, and from 180 to 300% for professional options.

The coefficient depends on various reasons, for example:

• Indoor temperature;
• Air humidity;
• Foam speed;
• Application method;
• User experience and abilities.

As a rule, the material yield is indicated on the package, but the characteristics are valid subject to the rules and favorable circumstances.

Foam expansion is primary and secondary. One is observed when the material leaves the balloon, the other occurs after the completion of the process. If the product is of high quality, then the secondary expansion will be approximately 20-30%.

If this property is taken into account, then the foam will not leave the cavity, but will remain inside and fill everything qualitatively.

Foams with a low re-expansion rate are suitable for installing windows and doors, since no deformation will be observed when the material dries. Excessive foam pressure in this job is unacceptable. To avoid troubles when installing structures, you should pay attention to the following qualities of foam.

Low re-expansion will prevent void filling in structures. For this work, it is better to use household materials. Professional foam is best used with a gun. Any polyurethane foam should not remain in open areas. The material must be protected from ultraviolet radiation.

In addition to the expanding properties, shrinkage is observed in some species. For high-quality material, it should not exceed more than 5%. Large shrinkage leads to deformation of the mass, as well as breaks in the structure.

Another important property of an insulator is adhesion to other surfaces. The foam does not stick to inert substrates, for example:

• Teflon;
• Polyethylene.

The insulator is suitable for most materials used in modern construction.

Expert advice

Professionals recommend working with a balloon held vertically downward.Thus, the light gas will mix faster with other species and displace the foam. For best performance, the container needs to be shaken occasionally.

To prevent gas leakage during storage, the cylinders must be installed with the valve position up. The ambient temperature should be +5 - +25 degrees.

Holes in structures, both hidden and obvious, are best foamed with ordinary household polyurethane foam. Technologically complex structures are best handled with professional compositions.

Window and door blocks should be secured with special mounting insulators. Manufacturers usually present special lines for these purposes. The formulations are characterized by minimal secondary magnification.

If the place of foaming requires special fire resistance, then it is better to choose appropriate foams. When performing outdoor work, special attention should be paid to the seasonality of the insulator.
